CALENDAR DEVICE.

' Application and July 2s,

This invention relates to a calendardevice. It is aimed to provide an exceedingly compact construction which will constitute a novelty in addition to its handiness or usefulness and may be used in relatively small form, as on the ends of writing instruments either as an attachment or aninitial part thereof as a Watch charm, as a knob or handle on a clock and in various other relations.

The invention consists of various coacting parts which will show the year, the month,

the day and the number of days in the month.

The more specific objects and advantages will become apparent or be pointed out in the description following taken in connection with accompanying drawings illustrating an operative embodiment.

In said drawings: I Figure 1 is a side elevation showing the invention applied as an attachment to a fountain pen; I j

Figure 2 is an enlarged side elevation of the calendar device; 7

Figure 3 is a central vertical section taken through the calendar deviceon the same scale as Figure 2;

Figure 4 is a cross sectional view taken on the line 44 of Figure 3 v Figure 5 is a cross sectional View taken on the line 55 of Figure 3; 1

Figure 6 is a cross sectional view taken on the line 6 6 of Figure 3;

Figure 7 is a cross sectional view taken on the line 77 of Figure}, and

Figure 8 is a cross sectional view taken on the line 8-.8 of Figure 2.

Referring specifically to the drawings, the calendar device constituting my invention is generally designated A. By way of example, such device is shown used as an attachment on a fountain pen conventionally illustrated at B in Figure 1. The device is capable of general use as previouslymentioned and hence no limitation as to use on a fountain pen or writing instrument is to be inferred.

The device per se has a central body 10 of cylindrical form. This body may have a reduced lower end 11- whereby it may be fastened by upsetting at 12 to an attaching head 13 having interior screw threads 14. The threads 14 may engage those usually found at the top of the barrel of the fountain pen B and normally engaged by a cap thereon, which cap is discarded to accommodate the use of the calendar device. It is to be noted that the cap 13 need not be a separate piece 1928. Serial No. 295,404.

from the body 10 and further need not be detachable from the fountain pen but thatthe body 10 may be provided on the barrel of the ment longitudinally of the body 10 and of rotation thereon. Said sleeve 16 normallv however 1s 1n uppermost position in contact with the "under surface of disk 15 through the agency of an expansive spring 17 surrounding body 10', located in a recess 18 in the.

sleeve and abutting such sleeve and theattaching head 18,

Qn. the per] hery of the disk is an indication for each day of the week as at 19 and coacting therewith, the periphery of the sleeve 16 has seven vertical columns 20 of figures indicatingthe days of the month. The upper row has figures running from left to right from one to seven, the next row left vto right from eight to. fourteen, the next row to the right from fifteen to twenty-one, the .next row to theright from twenty-two to twentyeight and the next row to the right from twenty-nine to thirty-one, it being observed that the figures one, eight, fifteen, twentytwo and twenty-nine occur in the same vertical column. As a result of this construction, turning of the sleeve 16 enables the column containing one to be brought in line with the appropriate day atthe startin a I given month in 19. a o I j c Sleeve 16 is circumferentially grooved as at 21 to accommodate a rotatable, resilient clasp line with the day indications band 22, its frictional contact with the sleeve serving to hold it in different adjusted positions. A vertical enlargement23 constitutes a shield to conceal the numerals twenty-nine, thirty and thirty-one, or any of them, according to the number of days in a given month.

An outward projection 24 is struck in the V band 22 for engagement by the finger in adjusting it relatively'to the sleeve.

Corresponding with each of the seven day indications 19, the under surface of disk 15 has seven recesses or notches 25 provided therein and they are selectively engageable according to the registration desired between the indications 19 and the columns 20, by a lug 26 provided on the upper surface of the sleeve 16. The slidable mounting of the sleeve against the tension of the spring 17 element 28 are plates and 31. are movable independently and to facilitate their movement, lugs 32 and 33 are provided other months are concealed.

enables engagement and disengagement of the lug 26 and recesses 25. g

The upper surface of disk 15 has a depression or is countersunk as at 27 and, a rivet'or,

screw 28 is detachably or non-detachably secured cent-rally of the body 10 as preferred. Rotatably mounted on the shank 29 of said Said plates thereon, respectively. The upper surface of thedisk l5or base of its depression has segmental delineations for each month of the year 34,"as best shown in Figure 6. The plate 30 moves over the delineations 34 and has a segmental cut away portion, slot or wvindowat 35 of a size to expose one of the delineations 34 at a time. lhus as shown in Figure 5, January alone is exposed and the The plate 31 operates above and over the plate 30 and it has a window, slot or cut away portion at 36 through which delineations 37 of the plate30, may be seen or brought into registry one at a time. Such delmeations 37 may run con- 'secutively from twenty-eight to thirty-six or higher if preferred. Coaction with such delineations, 1s the numeral 19 as lndicated particularly in Figure 4. Thus with the window 1. A calendardevice of the class described having a body provided with a disk, a sleeve rotata'ble'on said body and slidable relatively to the disk, means maintaining the disk and sleeve in operative relation, one of the parts having a plurality of recesses, the other having a lug to selectively engage-the recesses, spring means engaging the sleeve and adapted to hold the lug in engagement with the "recesses, and-coacting calendar indications on the disk and sleeve adapted to be brought in registration and so held by said lug and recesses. v

1 2. A calendar'device of the class described having a body provided with a disk, a sleeve slidable and rotatable on'said body, means maintaining the disk and-body in operative relation, one of the parts having'apluralit'y of recesses, the other having a lug to selectively engage the recesses, and coacting" calendar indications on the disk and sleeve adapted to be brought in registration andso held by said lug and'recesses, said body having indications for the months thereon, a plate movable thereover having year indications thereon,-a window to expose said month indications, and a plate movable above the first mentioned plate having a window thereon to expose said year numbers, and a year number on the last mentioned plate to coact with the year numbers of the first mentioned plate.-

3. A device of the class described having an attaching head, abody extending therefrom provided w'th a disk, said disk having recessesin. its under surface, a sleeve slidable and rotatable on said body and having a,

projection to selectively engage said recesses, an expansive spring surrounding the body and engaging said sleeve and said attaching head to maintain the lug and recesses in' engagement, coacting calendar indications on said disk and sleeve, to show the arrangement of the days in a given month, the diskhaving a recess and provided thereinwith month indications, a plate in .said recess movable over said indications and having a window to expose the same one at a time, said plate having year numerals thereon, a plate movable over the first mentioned plate having a Window to expose said year numerals one at a time, and a year numeral on the last mentioned plate to coact with said year numerals.

Intestimony whereof I aifi'x my signature.
